Overview
Surgery is the mainstay of treatment for insulinoma. The feasibility of surgery depends on the stage of insulinoma at diagnosis.[1][2]
Surgery
Surgery is the mainstay of treatment for benign and resectable malignant insulinoma. It can be 100% curative in experienced surgical hands.
Benign Tumors
- Small well-encapsulated, solitary tumors:[1][2][3]Tumors is localised with palpation in 70 % cases during surgery. Intraoperative ultrasound(IOUS) localizes in 86% of times. Palpation and IOUS together localizes tumor in 83-98% cases.[4][5]
- Surgical resection is the treatment of choice. Minimal invasive surgery such as laparoscopic surgery is preferred especially for small and solitary benign insulinomas.
- Enucleation
- Partial pancreatectomy
- Distal pancreatectomy
- Pancreaticoduodenectomy[6]
- Multiple, unencapsulated, >4 cm in diameter, and involves or is near the main pancreatic duct:
- Radical resection
- Insulinomas which are associated with MEN1, excision of tumor found in the head of the pancreas plus a distal subtotal pancreatectomy is recommended.[7]
- For occult insulinomas, blind distal pancreatectomy is not advisable.[8]
Malignant Tumors
- Aggressive surgical resection, including extended pancreatic resection with lymph nodes, liver resection, and/or liver transplantation
- Post-surgical chemoembolization or radiofrequency ablation of tumors to control hypoglycemia
- Unresectable tumors
- Octreotide administration
- Continous glucose monitoring
- Radiofrequency ablation
- Embolization
- Intra-arterial chemotherapy
Indications
- Repeated and prolonged symptoms of hypoglycemia
